What's new about the 480? It's been on the market as the Garmin 480
(with WAAS and C146 certification) for nearly four years now and is
identical to the UPSAT branded units before that. There' has been
one whopping software revision in the interim (the one that fixes the
256 LPV approach limit).

That unit was specifically mentioned by AOPA as not approved.

I was thinking of getting one of them. I wonder what the difference is.

Its totally different software. Flying behind the 480 you wouldn't
even think it was a Garmin product (in fact it wasn't until Garmin
bought it). However, I believe it was the first WAAS approved GPS and
it also has cool things that the 430 forgot (user defined holds,
airways, etc).
